Patented May 20, 1930 unrrsn STATES ANDREW W. LOVEJOY, OF KANSAS CITY, MISSOURI WINDOW SCREEN Application filed February 29, 1928. Serial No. 257,837.

This invention relates to window screens of that general class composed'of'metal corner sockets and side and end bars of wood or the like.

My object is to produce a strong and rigid] be readily secured regardless of whether the ends of said bars are squared or mitered. A

still further object is to provide sheet metal corner sockets which tend to prevent water from gaining access to the extremities or raw ends of the bars of the frame so that the period of service of the latter shall be materially lengthened. Another object is to produce a screen which can be manufactured and sold in quantity at an appreciably lower figure than the conventional type of wood screen in which the bars at the corners are mortised and nailed or dove-tailed together, and a still further object is to provide frame parts which can be conveniently assembled in bundles for economy in shipment.

With these general objects in view, the invention consists in certain novel and useful features of construction and combination of parts as hereinafter'described and claimed; and in order that it may befully understood reference is to be had to the accompanying drawing, in which:

Figure l is an outer face view of a window screen embodying the invention.

Figure 2 is a full size elevational view of one corner of the screen as viewed from the inner side thereof.

Figure 3 is a section taken on the line IIIIII of Figure 2.

Figure 4 is a perspective view of one of the corner sockets "of the screen.

F i ure 5 is a reduced view of a blank from whic a corner socket is produced.

. Referring now to the drawing in detail, and particularly to the socket feature of the screen to be die formed from sheet metal, 1 indicates a right-angle shaped body, the 50 arms thereof being identified by the characters 2 and 3. At the inner angle of the body is a correspondingly shaped but narrower extension bisected diagonally to provide similar flanges 4 and 5 for the arms 2 and 3 respectively, said flanges 4 and 5 being adapted to be bent along the junction lines thereof with the arms 2 and 3, to stand at right-am gles to said arms and form inner edges or walls for the socket.

The body portion is provided at the oppo- (50 site side from flange or wall 4, with an extension in width corresponding to the combined widths of arm 2 and flange 4, and said extension on the dotted line 6 paralleling arm 2, is adapted to be folded to provide an outer edge or wall 7 and an inner side wall 8 for the socket, the end of the wall 8 opposite the arm 3 being of arcuate form as at 9 and extending angularly between points in line with the outer corner and inner corner of body portion 1. V At the opposite side of arm 3 from flange or wall 5, the body portion is provided with an extension equal-in width to the combined widths of arm 3 and flange or wall 5, and 7 said extension is adapted tobe folded on the dotted line 10 to provide an outer edge wall 11 and an outer side or face wall 12, and the last-named wall is diagonally bowed at one end as at 13 in the same manner as described so with reference to the bowed or arcuate end 9, and the wall 11 between the adjacent arcuate ends 9 and 13, is formed with a'foldable extension lug 14.

Wall 8 is provided at the opposite side thereof from wall 7, with an oblong rectangular extension 15 adapted to form an inner wall and eventually fit flatly against wall 4, and said extension or wall 15is provided at the end adj acentthe arcuate end 9 of wall so 8, with an extension lug 16, and near its other end with an extension lug 17, the lug 17 extending laterally at right angles to lug 16. Wall 12 is provided at its opposite edge from wall 11 with an oblong rectangular extension 18, provided at its end adjacent its arcuate end 13 with a lug 19, and near its other end with a laterally-projecting lug 20.

To fold the blank described so as to produce a corner socket, arms 4 and 5 are folded along the inner margin of the arms 2 and 3 respectively to positions at right angles to the body portion, see dotted lines Figure 5. The blank is then folded at the junction of arm and wall 7 until the latter stands at rightangles to the body portion and parallel with the folded arm t. The extension is then bent along the dotted line 6 until portion 8 stands in parallel relation to the body portion. At the junction of portion 8 and portion 15 an other fold in the same general direction is made so that portion 15 shall enclose and fit fiatly against arm 4-, it being necessary however before this last fold is made, to first fold lug 16 at right angles to portion 15, so that when the latter is folded as explained, the lug 16 shall. enclose and fit flatly against the folded flange been arranged as explained, the lug 17 is folded so as to fit fiatly against the arm 2 of the body portion, thus completing one arm of the socket.

The manipulation described with reference to portions 7, 8, 15 and lugs 16 and 17, is

followed with respect to portions 11, 12, 18.

and lugs 1.9 and 20, it being noted that lug 19 is like lug 16, bent at right-angles to portion 15, so as to enclose and fit at the inner side of arm 15 before the portion 18 can be caused to enclose and overlap the arm 5, it being noted that when the folds are completed the lug 16 is interposed between flange 5 and arm 18, and that lug 19 is fitting against the opposite side of arm from arm 1, thus completing the other arm of the corner socket. It will be seen that at the inner corners of the socket, the material is of three-ply or thickness to impart great strength and rigidity, and that the inner edge walls of the socket are of double strength. At the outer corner of the socket where the ends of the walls 11 and. 7 come together in the folding operation, the lug 14: is bent over the adjacent end of wall 7 so as to close said joint and stiffen the corner. At the side which is preferably termed the outer face, the bowed ends 9 and 13 of portions 7 and 12 are in overlapping relation, the bowed end 13 overlapping the bowed end 9, it being noted by reference to Figure 1 that the corner sockets can be so arranged that the overlapping bowed ends 1?) shall always face in a downward direction tending to shed water running down or beating upon the screen, so that such water shall be prevented from entering the socket between said overlapping bowed. portions.

The blanks of the type described may be folded by hand, but it is contemplated that they shall be folded automatically, as by the use of forming dies the folding operations can be accomplished with greater accuracy and of course with far greater rapidity and economy.

Referring now to Figures 1 to 3 inclusive, A represents the sides or bars of a screen After the portion 15 has frame, said bars being fitted at their ends in the sockets. WVhen thus fitted, it is desirable that nails shall be driven through the various exposed lugs 14,17, 19 and 20, and the interposed parts of the socket into the frame bars, and to insure the most effective placing of the nails, the sockets are provided with holes for nails B for uniting the sockets with the bars, which nails will prevent the various lugs from being readily sprung or pressed out by catching on other objects in handling and in shipment. The nails furthermore make the frame perfectly rigid by guarding against any possibility of the frame spreading more at one end or side than at the opposite end or side, as each socket is. nailed at one or more points to the adjacent ends of two of the bars and thus unite all of the bars together as a unitary or integral structure. It is obvious of course, that the nailing operation can be performed without providing holes in the blank, as the metal is thin and can be readily punctured bv the nails as the latter are applied and that with proper metal and equipment the lugs and other overlapping parts can be so accurately bent and applied that the nailing operation can be dis.- pensed with entirely.

Then the skeleton frame composed of the bars and sockets is completed, screening material C is placed upon the frame and tacked or otherwise secured thereto, and to provide a finish for the frame by covering the raw edges of the gauze, and to, assist in holding the latter in place, batten strips D are fitted over the marginal portions of the gauze and tacked in place as conventional in screen practice.

In Figure 2 it will be noted that the ends of uxtaposed bars A are shown as mitered at their meeting edges in full lines and as having squared ends in dotted lines. For economy and equal efficiency the squared ends are preferred, especially for screens which are to be shipped in knocked-down condition, as the squared ends are less susceptible to injury than bevelled ends, and it is contemplated that the four sides and four batten strips for each screen, shall be tied together in a bundle for shipping purposes. Screening material may be shipped in a roll or may be obtained locally by the purchaser so as to avoid the expense of shipment of the screen material. Associated with each bundle of bars and battens will be one set of corner sockets which by preference will be shipped in completed form and ready for the reception of the bars to be applied by the purchased, if desired, as anyone can assemble the parts of a screen of this character properly and easily, the only point on which instructions may be needed, being to suggest that it is preferable to arrange the four corner sockets so that the arcuate IOU ends hereinbefore mentioned shall be at the outside of the screen with the overlapping arcuate end portions facing downward to facilitate the shedding of Water, as herein before mentioned.

It will be noted by comparison of Figures 2 and 4, that in the former the lug 16 is tering between said overlapping portions.

This also results in disposing the flanges 14 of the two upper sockets, in a depending posit-ion and the flanges of the right-hand socket of the lower pair in a horizontal position under the said sockets,the flange 14 of the left-hand lower socket extending upward.

It is obvious of course, that all of the sockets may be identical in all respects, but that in such case, it will result that two sockets of each set will have their sides 23 at the outer face of the screen and the other two at the inner face of the screen; this arrangement being undesirable as detracting from the appearance of the screen if closely scrutinized.

From the above description, it will be apparent that I have produced a screen which embodies the featuresofadvantage set forth as desirable in the statement of the objects of the invention, and which is susceptible of modification in minor particulars without departing from the principle of construction and mode of operation involved or from the spirit and scope of the appended claims.
